I like the concept of the story a lot, BUT THIS IS NOT FUCKING AVATAR! Have you EVER seen them go all Katara and be ableto do whatever they wanted with water or any other jutsu? Ever? They have alwaysused jutsu to attack only, nothing else was really shown exceptthe few oddball jutsu.

Hey, Mitsuki! I got a present for you. (Tosses a key) This key is to something I sealed 2,000 years ago. It's a vault of chocolate. Dark, White, Milk, hell it's even got Hellflame Chocolate, one that, supposedly, only the Dragon Lord Bahamut could eat and not feel any side effects. Of course, he had me seal it.

Kaaru, this is for you. (Tosses a box) In that box is something that opens the door next to the one she can open. You want cookies? I'll give you one better... More like 5 better. Go! Tame the SUGAR RUSH!

Naruto, I'd give you a summoning contract, and the Kyuubi might like it, but unfortunely it's not my story. Sorry!
